BOX-BASE FOB BADIATORS'.

Specification of Letters Iatent. Patented Oct. 28, 1919- Application filed August 13, 1917. Serial 1T0. 186,074.

. To all whom it mayconoem Be it known that I, THOMAS H. WALKER, a citizen of the. United States, residing at Kansas City, in the county of Jackson and State of' Missouri, have invented a certain new and useful Improvements in Box-Bases for Radiators, of which the following is provide a box base which is adapted, for

use in connection with low setting radiators, which may be cheaply manufactured, which is durable and not liable to get'out of order. and which may be easily operated.

' The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing which illustrates thepreferred embodiment of my invention,

Figure 1 is a side elevation of my 1mproved box base shown applied to a radiator.

Fig. 2 is an end elevation of what is shown in Fig. 1.

Fig. 3 is a vertical sectional view, enlarged, on the line 3-3 of Fig. 1, the radiator being omitted. v

Fig. 4 is an enlarged horizontal sectional view on the line 4-4 of Fig. 3.

Fig. 5 is an enlarged horizontal sectional view on the line 55 of Fig. 3.

Fig. 6 is a top view, reduced, of my 1mproved box base.

Similar reference characters designate similarparts in the different views.

1 and 2 designate respectively the front and rear side walls ofthe box base, the walls 1 and 2 being provided at their lower ends respectively with two oppositely disposed air inlets 3 and 4, adaptedto respectively receive air from the room which is being heated and from the outside thereof. 5 designates the two end walls of the casing which are adapted to be disposed vertlcally between two sets of sections 6 of the steam or hot water radiator of an ordinary type.

Secured respectively to the inner sides of the end walls 5 are two arcuate guides 7, located between the air inlets 3 and 4, and disposed with the convex sides down.

Shdably engaging the guides 7 is a valve 8, preferably arcuate and adapted to be moved to positions closing or partly closing either of the inlets 3 or 4. 1

The valve 8 is shown in solid lines in Fig. 3, closing the inlet 3. In said figure, it is shown, in dotted lines closing the inlet 4.

For sliding the valve 8 on the guides 'Z I provlde a link 9, Fig. 3, which is preferably flexible and resilient, which has its lower end secured to the valve 8, and which has its upper end clamped between two nuts 10 and'll, Fig. 2, which are mounted on a horizontal screw 12 which extends through the link 9. and which extends through and is vertically slidable in a vertical slot 13, which is provided in the front wall 1 of the box base. I

The nut 11 is at the inner side of the wall 1 and is adapted to be clamped against said wall by means of a thumb nut 14 which is mounted onthe screw 12 at the outer side of the wall 1, against which it is adapted to be releasably clamped.

The outer end of the screw 12 is provided with a head, which prevents the thumb nut 14. from being screwedentirely off from the screw 12. The nuts 10 and 11 serve as lock nuts which prevent the screw 12 from turning. when the thumb nut 14 is turned.

When it is desired to close the inlet 4 and open thev inlet 3, the thumb nut 14 is loosened and forced downwardly, thereby forcing the screw 12 downwardly in the slot 13, and thereby sliding the valve 8 to the position shown in dotted lines in Fig. 3, through the intermediacy of the link 9. The latter is. preferably. flexible and resilient' to permit of its bending. When the valve 8 has been moved to the desired position, the thumb nut 14 is turned so as to tightly clamp itself and the nut 11 against the wall 1. b

Each of the walls 1 and 2 at-its inner side is preferably provided with two clips 15 adapted to respectivelyreceive the adjacent downwardly turned ends of two horizontal cross braces 16, which serve as spacers for the upper ends of the walls 1 and 2.

In setting up the box base, the inlet portion 4 of the casing may be inserted through an opening provided in the adjacent wall 17 as shown in Fig. 8.

With the valve 8 closing the inlet 3 as shown in solid lines in Fig. 3, air from outside of the room will enter the box base through the inlet 4 and will thence pass upwardly between the sections -6 of the radiator.

When the valve'8 is moved to the position shown in dotted lines in Fig. 3, air will pass from the roof containing the radiator through the inlet 3 and thence upwardly.

sired position.

In order that the valve 8 may tightly close at both ends of its stroke, and yet swing freely after leaving either of said positions, flanges 18 are folded over the convex side of the valve at its longitudinal edges respectively, see Fig. 3. The flanges 18 are adapted to bear against the upper side of a bottom plate 19, with which the base is provided, when the valve is swung to the two positions shown in solid and dotted lines in Fig. 3.

As soon as the valve is slid from either of these positions, to a position in which neither flange 18 will strike the plate 19, the valve will not touch the plate 19, thus eliminating much friction in the operation of the valve, while permitting 9. t1 ht joint between the valve and bottom plate when the valve is at either end of its stroke.

I do not limit my invention to the structure shown and described, as modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention. I

"What I claim is 1. In a box base for radiators, a casing having two inlets for air at opposite sides thereof respectively, two arcuate guides being provided on the easin intermediate of said inlets, a valve slidab e on said guides to positions closing either of said inlets, a releasable locking device slidably mounted upon said casing and having means for being releasably clamped thereto, and a linkv ed in said base, a link connected to said screw and to said valve for sliding the latter, clamping means carried by sa1d screw and adapted to clampingly engage said link, and anut mounted on-sa'id screw for moving the same with said link and adapted to releasably clamp said base.

3. A box base for radiators having two air inlets and provided with two arcuate guides, and having a vertical slot, a valve slidable on said guides to positions closing either of said inlets, a screw extending through and slidable in said slot, releasable means carried by said screw for clamping said base, and a link connecting said valve and said screw.

4. A box base for radiators having an inlet for air, and havin two arcuate guides, a valve slidable on sa1d guides, a manually operable member rectilinearly movable on said base, and a flexible link connecting sa1d member and said valve, the valve being movable by said link to and from a position closing said inlet.

5. A box base for radiators having an inlet for air and two arcuate guides, a valve slidable on said guides to and from a position closing said inlet, manually operable means slidable on said base and having provision for being releasably clamped thereto, and a link connecting said means and said valve.

6. A box base for radiators provided with a casing having ,two side walls respectively provided with two air inlets, one of the side walls having a vertical slot, the end walls of the casing being provided respectively with two arcuate guides, a valve slidable on said guides to and from positions closing either of said inlets, a member extending through and slidable in said slot, means carried by said member, for releasably clamping said casing, and a link connecting said member and said valve.

7. In a box base for radiators, a casing having a bottom plate and two inlets for receiving air, and a valve movable to two positions in which it will respectively close said inlets, the valve in either of said-positions bearing against said bottom plate, and intermediate of said positions being clear of the bottom plate.

8. In a box base for radiators, a casing having a bottom late and two inlets for air and provided wit two arcuate guides, and a valve slidable on said ides to positions respectively closing said inlets, and in said positions bearing against the bottom plate, and intermediate of said positions being clearof the bottom plate.

' In testimony whereof I have signed my I name to this specification.
